FIGURE 1. Resolution was iteratively degraded in two ways. The grid represents pixel density, the physical size of the image represents magnification. The top image represents the maximum pixel density and maximum magnification. In the lower left, the same wear surface is sampled at the same magnification but with a lower pixel density. In the lower right, the same wear surface is viewed with a lower magnification, also resulting in an equivalent decrease in pixel density with respect to the tooth surface.

FIGURE 2. Resulting resolutions from iteratively reduced pixel density (left column) and reduced magnification (right column). These images are best viewed while zooming in on a computer display.
